The company has provided few details so far about the project, which is part of a $214 million effort to improve the power transmission system throughout Greater Portland, including substation proposals in Freeport, North Yarmouth, Cumberland, Gray and Portland.
The plan to upgrade what’s called the Cape Substation comes as the city tries to control development in its increasingly popular waterfront neighborhoods, including a 2014 ban on loading crude oil into tankers that the Portland Pipe Line Corp. is challenging in federal court.
The city has petitioned the Maine Public Utilities Commission to intervene in its ongoing review of CMP’s Brightline Initiative – the company’s long-term effort to meet state and federal requirements for power reliability and develop an energy grid that can support growth in renewable energy.
Maine’s public advocate skeptical of $2.5 billion plan to ‘harden’ power grid
Avangrid is proposing a $2.5 billion effort in Maine and New York, and at least some of the costs would be borne by ratepayers under the proposal.
Gail Rice, spokeswoman for the utility, said cost details are still being sorted out. But she said the company wanted customers to know that a plan is in the works to boost the reliability of the Maine power grid.
